<div class="textblock"><p>Base class for items on the plot canvas. </p>
<p>A plot item is "something", that can be painted on the plot canvas, or only affects the scales of the plot widget. They can be categorized as:</p>
<ul>
<li>Representator<br  />
 A "Representator" is an item that represents some sort of data on the plot canvas. The different representator classes are organized according to the characteristics of the data:<ul>
<li><a class="el" href="class_qwt_plot_marker.html" title="A class for drawing markers.">QwtPlotMarker</a> Represents a point or a horizontal/vertical coordinate</li>
<li><a class="el" href="class_qwt_plot_curve.html" title="A plot item, that represents a series of points.">QwtPlotCurve</a> Represents a series of points</li>
<li><a class="el" href="class_qwt_plot_spectrogram.html" title="A plot item, which displays a spectrogram.">QwtPlotSpectrogram</a> ( <a class="el" href="class_qwt_plot_raster_item.html" title="A class, which displays raster data.">QwtPlotRasterItem</a> ) Represents raster data</li>
<li>...</li>
</ul>
</li>
<li>Decorators<br  />
 A "Decorator" is an item, that displays additional information, that is not related to any data:<ul>
<li><a class="el" href="class_qwt_plot_grid.html" title="A class which draws a coordinate grid.">QwtPlotGrid</a></li>
<li><a class="el" href="class_qwt_plot_scale_item.html" title="A class which draws a scale inside the plot canvas.">QwtPlotScaleItem</a></li>
<li><a class="el" href="class_qwt_plot_svg_item.html" title="A plot item, which displays data in Scalable Vector Graphics (SVG) format.">QwtPlotSvgItem</a></li>
<li>...</li>
</ul>

<p>Before misusing the existing item classes it might be better to implement a new type of plot item ( don't implement a watermark as spectrogram ). Deriving a new type of <a class="el" href="class_qwt_plot_item.html" title="Base class for items on the plot canvas.">QwtPlotItem</a> primarily means to implement the YourPlotItem::draw() method.</p>
